How Keynesianism became a dirty word: not Hayek, the New Deal is the real cause

Noah Smith, now writing regularly for Bloomberg, had a piece on this subject. There are a few good points on how New Keynesians are really followers of Friedman, something Mankiw admitted long ago, and how everybody including conservative economists (meaning GOP economists like John Taylor and Ben Bernanke) are New Keynesians (these would be the potty trained GOP economists, not your supply-side fringe economists like Arthur Laffer). Note that this is essentially correct as pointed out here before, since New Keynesians accept fully Friedman's notion of a natural rate of unemployment, while Keynes explicitly said he wanted to reject the twin concept of a natural rate of interest.

Noah also suggests that Keynes only wanted stabilization policies, and no redistributive policies, which is more open to debate. Keynes was certainly a moderate reformer trying to save capitalism from itself, and was no fan of the Soviet experiment. On the other hand, he was an Asquith liberal, meaning concerned with the expansion of the welfare system, and knew that laissez-faire, if it had advantages in the past, was essentially dead.

In the General Theory (GT) he famously starts chapter 24, on his social philosophy, with the idea that: "the outstanding faults of the economic society in which we live are its failure to provide for full employment and its arbitrary and inequitable distribution of wealth and incomes." That is, income distribution is squarely in the middle of his preoccupations, and the socialization of investment at the center of his solution (let alone the euthanasia of the rentier). Using public investment, and one would imagine taxes, to deal with employment and income distribution, plus compressing the remuneration of rentiers, and keeping low rates of interest to expand the safety net, are not simply stabilization policies.

On the main topic of his piece, however, Noah is simply wrong. He argues that the reason why: "people think Keynesianism is socialism-lite [is] the fault of Keynes’s main intellectual opponent, Friedrich Hayek." First, while it's true that Keynes and Hayek had a few debates in the 1930s (but the key Keynesian author in these debates was actually Sraffa, not Keynes), prompted by Lionel Robbins plan to make the London School of Economics (LSE) an alternative to Cambridge, it is preposterous to say that Hayek was the main intellectual opponent of Keynes. In the GT, it was his own teacher Pigou, and the Marshallian tradition in Cambridge that Keynes was battling. In his personal debates Robertson was certainly more relevant than almost any other conventional (Marshallian) economist. Hayek was irrelevant.

Second, Hayek basically vanished, literally, after the 1940s only to reaper in the 1970s as a result of his dubious "Nobel"/Bank of Sweden's prize (see Sissela Bok's, Myrdal's daughter, story on that topic). By that time Keynes and Keynesianism were already dirty words. Early on Keynesian ideas were associated, fairly or not, with Roosevelt and the New Deal in the US, and then to the war coalition government in the UK, the Beveridge Report and the post-war Labour reforms. Keynesian economists were in many cases persecuted, like Lauchlin Currie, the first economist to work inside the White House, and one of the early Keynesians. But by the 1950s and 1960s (particularly after the Kennedy administration) one kind of Keynesianism was dominant anyway (the Kennedy tax cut and the economists working for his administration are the symbol of the dominance of Keynesian ideas).

So you ask why indeed did Keynesianism become a dirty word? Simply because even if Keynes had differences with Roosevelt (FDR was actually a sound finance guy) and with Labour, his ideas did provide the intellectual basis for New Deal policies, particularly after the 1937-38 recession, and for the expansion of the Welfare State in general. The economists that where against these policies by the 1940s were in the minority. Mont Pelerin is, if anything, prove of their sheer irrelevance. Friedman years later would complain about how ostracized he was (but less than Hayek, since he accepted the ISLM/Phillips curve apparatus of the Neoclassical Synthesis Keynesians; and that's why New Keynesians, who are really followers of Friedman, can say they are Keynesian, by the way). Liberalism, in the US sense of the word, was at its height. But the rise of conservatism (Goldwater was a joke back then) eventually transformed liberalism into a dirty word (that's why we use progressive now rather than liberal).

Hayek was resuscitated very much like conservative ideas. By the big bucks of business leaders and their think tanks that were against the New Deal. The rise of Hayek or of his renewed respectability results from the same forces that explain why Keynesianism and the New Deal kind of welfare policies fell in disrepute, to the point that Niall Ferguson could say that Keynesianism was flawed because Keynes was childless and gay. Oh well.

PS: In fact, the title of this blog is related to the view that Keynesianism is a dirty word, and that some people (Galbraith) unashamedly teach naked Keynesianism to innocent college kids. For more see here.

Noah has a tendency to refer to YouTube videos for insight into economic history. So this very well may be his source:

I think you're correct about why "Keynes" became a dirty word among economists, and that Hayek had nothing to do with it. I suspect that for the general public, though -- the kind of people Noah hears using "Keynesian" as a synonym for "socialist" -- it probably has to do with the popular economist writers (J.K. Galbraith back in the day, Krugman now) known to be "Keynesian" also being reliable lefties. Since both are on the record as being in favor of more public spending and intervention, that must be what "Keynesianism" is about (never mind that Krugman only favors this when nominal interest rates hit zero).

So besides the coup in Brazil (which was all but confirmed by the last revelations, if you had any doubts), and the electoral victory of Macri in Argentina, the crisis in Venezuela is reaching a critical level, and it would not be surprising if the Maduro administration is recalled, even though right now the referendum is not scheduled yet.

The economy in Venezuela has collapsed (GDP has fallen by about 14% or so in the last two years), inflation has accelerated (to three digit levels; 450% or so according to the IMF), there are shortages of essential goods, recurrent energy blackouts, and all of these aggravated by persistent violence. Contrary to what the press suggests, these events are not new or specific to left of center governments. Similar events occurred in the late 1980s, in the infamous Caracazo, when the fall in oil prices caused an external crisis, inflation, and food shortages, which eventually, after the announcement of a neoliberal economic package that included the i…

So, a few days ago, someone (my bad, can't remember who did it) posted on FB a piece (in Portuguese and behind a wall; but this post is mostly about the role of historical comparisons really, so you can skip the piece altogether) on the Brazilian National Development Bank (Portuguese acronym is BNDES, btw) and how it lend more than the US government with the Marshall Plan. The guy did a back of the envelope calculation (I did check and bringing the US$ 13 billion to present value, with the GDP deflator would be about 106 billion, roughly what he calculated) and concluded that the BNDES lending, which was higher, was very ineffective. Hm. Where to start?

Sure one can assume that the important thing is just to calculate how much money was lent in current values and one gets a reasonable picture of the impact. However, it should be clear that the US was lending dollars, and access to imports that were vital for the survival of Europe. Harder to put a dollar figure on that. But a bet…
